Iingenelo ezininzi zeevalvu zebhola zePVC zibenza ukhetho oluhle kakhulu kwiinkqubo ezahlukeneyo.Kukho izinto ezithile ekufuneka ziqwalaselwe xa uthatha isigqibo sokuthenga ivalve yebhola, ngakumbi aIvalve yebhola yePVC.Nangona i-PVC ikwazi ukumelana neemeko ezahlukeneyo, umdlalo ofanelekileyo phakathi kwevalve kunye nesicelo kubaluleke kakhulu xa ukhetha i-valve yebhola ye-PVC.

Ukukhetha ivalve yebhola yePVC
uyilo lomngxuma
Ngelixa i-valve ye-PVC yeendlela ezimbini iyona ixhaphake kakhulu, kukho ezinye iiplani zemingxuma ezinokunceda ukuphucula ukusebenza kwesicelo.Uyilo lweendlela ezintathu zokuzala lubandakanya ulungelelwaniso lwe-T-port kunye ne-L-port ukwenzela izicelo apho ukuhamba kwamanzi kuxutywa, kusasazwa, kwaye kuguqulwe.Olu luyilo lomngxuma luluncedo kakhulu kumanzi amaninzi kunye neentlobo ezahlukeneyo zokuhamba.

ukuqonda amajelo eendaba
Esinye sezizathu zokuphuhliswa kweevalve zebhola ze-PVC kwiminyaka ye-1950 yayiyimithombo yeendaba efuna ukuphathwa okukhethekileyo.Iivalvu zebhola ze-PVC zifanelekile kumajelo atshabalalisayo njengamanzi etyuwa, i-acids, i-alkalis, izisombululo zetyuwa kunye nezinyibilikisi eziphilayo, ezinokonakalisa ezinye izinto.Ukuqonda iimpawu ze-medium yinkalo ebalulekileyo yenkqubo yokukhetha.

I-Coefficient yobushushu
Iqondo lobushushu ngumba ophambili kwizicelo ezininzi zokuvelisa kwaye kufuneka ziqwalaselwe ngononophelo xa ukhetha ivalve yebhola yePVC.Ubume bekhemikhali bezinto zePVC yinto ekhokelayo xa ukhetha i-valve yebhola ye-PVC, njengoko i-PVC ilungele ukuthotywa kunye nokutshintsha phantsi kweemeko ezithile.

iziphumo zoxinzelelo
Ngokufana nobushushu, uxinzelelo lunokuchaphazela ngamandla ukufaneleka kweIvalve yebhola yePVCisicelo.Kule meko, ubume bePVC bunokuba yinto ethatha isigqibo.

ukuququmbela
Ivalve yebhola ye-PVC okanye i-polyvinyl chloride yivalve yeplastiki ephumayo enebhola ejikelezayo enomngxuma omisa ukuhamba kweendaba ngokujika ibhola kwikota.
Undoqo weIvalve yebhola yePVCyibhola ejikelezayo, ebizwa ngokuba yibhola ejikelezayo.Isiqu esiphezulu sebhola yindlela ejika ibhola, enokwenziwa ngesandla okanye ngokuzenzekelayo, kuxhomekeke kuyilo lwevalve.
Iindidi ezahlukeneyo zeevalvu zebhola zePVC ziyilelwe ukuhlangabezana nezicelo ezithile.Zihlelwa ngenani lamazibuko, uhlobo lwesihlalo, ukuhlanganisana komzimba, iipaseji zebhola kunye nobukhulu bebhore.
Izinto ezisisiseko zevalve yebhola ye-PVC yi-polyvinyl chloride, eyi-vinyl resin.Igama elithi PVC libhekisa kwizinto ezahlukeneyo zePVC ezinamandla ahlukeneyo, iipropati kunye neempawu.
Ukusetyenziswa okuqhelekileyo kweevalvu zebhola ze-PVC kukunqumla okanye ukudibanisa imidiya kwimibhobho kunye nokulawula ulwelo kunye nommiselo.
